Formation of a complex sentence

August 12th, 2010 in English Grammar, English Learning

A complex sentence has at least one main clause and one or more subordinate clauses. The subordinate clause may be a noun clause, an adjective clause or an adverb clause.

We need justice. That should be known to everybody.

That we need justice should be known to everybody. (Here the noun clause ‘that we need justice’ is the subject of the sentence.)

The above sentence can also be written with a preparatory it.

It should be known to everybody that we need justice. (Here the noun clause ‘that we need justice’ is used in apposition to it.)

More examples are given below.

He had been promoted. I told him that.

They proposed to do so. I was surprised at that.
